Modular storage case

ABSTRACT

A modular storage case is described, which is suitable for storage of a folded display stand. The storage case comprises a graphics storage case, and a frame storage case. The frame storage case has an external cross-section which is complementary to the shape of the graphics storage case. A storage case is also described, which is suitable for storage of a folded display stand, in which a reusable packing piece is provided for retaining equipment within the case. A packing piece is also described, for use in such a storage case.

[0001] The present invention relates to the field of storage cases, andmore particularly to storage cases suitable for the storage of a foldeddisplay stand.

[0002] Folding display stands are commonly used at exhibitions, tradefairs and so on. They typically comprise a lightweight folding metalframework which can be covered with graphics (being printed displaymaterial similar to posters).

[0003] In the particular application of small folding display stands,the display stand should be capable of being transported, assembled anddisassembled by a single person. For this reason, the display standshould be capable of being transported in the boot (trunk) of a car.

[0004] It is preferable to transport and store the folded display standin some sort of case, to protect both the frame and the graphics fromdamage.

[0005] During the exhibition, the case needs to be either hidden ordisguised, since otherwise it would represent unnecessary and unsightlyclutter, which would detract from the visual appeal of the stand. Somecases are used as counters or display items in themselves, if they arewrapped in a graphic.

[0006] However, known cases for such display stands have a number ofdrawbacks. While a single frame may be used for many exhibitions, it maybe necessary for different sets of graphics to be used. Typically, thestorage case contains the graphics rolled up, with the folded frameplaced in the void in the centre of the rolled graphics. To interchangetwo sets of graphics, therefore, requires the case to be unpacked, thegraphics removed, a replacement set of graphics to be rolled up andplaced in the case, and the frame placed inside. Once this has beenrepeated a number of times, it is clear that the graphics, and theframe, may suffer damage from excessive handling.

[0007] A known alternative, to provide a dedicated case and frame foreach set of graphics, may be prohibitively expensive.

[0008] In addition, the mere fact of storing the folded frame in thecentre of the roll of graphics may cause damage to the graphics duringtransport and storage.

SUMMARY OF THE INVENTION

[0009] The invention therefore provides a modular storage case withseparable cases for the frame, and for the graphics. The graphics casemay be interchanged with other graphics cases for transport to adifferent exhibition, while avoiding the need to unpack any of thecases. This reduces damage to the graphics and the frame by reducing theamount of handling required.

[0010] A second aspect of the invention relates to the avoidance ofdamage to either or both of a frame, and a roll of graphics. One or morepacking pieces may be provided in each graphics and/or frame case, toprevent the folded frame or other equipment from moving within therespective case, when it is handled.

[0011] In accordance with the present invention, there is provided amodular storage case for storage of a folded display stand, comprising agraphics storage case, having a substantially cylindrical internalstorage space; a first frame storage case, having an externalcross-section which is complementary to an external shape of thegraphics storage case; closure means for closing the graphics storagecase and the frame storage case; and fastening means for detachablyfastening the graphics storage case to the frame storage case.

[0012] The modular storage case may further comprise a second framestorage case, having an external cross-section which is complementary tothe external shape of the graphics storage case; further closure meansfor closing the second frame storage case, and further fastening meansfor fastening the second frame storage case to the graphics storagecase, at a location separated from the first frame storage case.

[0013] In either example, the closure means may incorporate thefastening means.

[0014] The closure means may comprise end pieces of suitable shapes forthe graphics case, and the frame case, and the fastening means may takethe form of co-operating features of the respective end pieces. If so,an end-piece for the graphics case may comprise a cylindrical, and/ortruncated conical, boss on its internal surface, for retaining storedgraphics, at least part of the external surface of the end-piececomprising a cavity corresponding to at least part of the boss.Furthermore, the end-piece for the frame storage case may comprise anoverlap portion, not required for closing the frame storage case; theoverlap portion being sized to overlap at least part of the cavity ofthe end-piece of the graphics case when the cases are placed together.The overlap portion may comprise a retaining lug suitably dimensioned tolocate within the cavity, when the cases are placed together, thereby toengage the cases to each other. The upper end pieces may be dimensionedsuch that the overlap portion has a thickness substantially equal to thedepth of a recess of corresponding shape located in the graphics caseend-piece, whereby the two end-pieces, when engaged, form asubstantially flat upper surface.

[0015] Similar arrangements of end-pieces, cavities, overlap portionsand retaining lugs may be provided at corresponding upper and lower endsof the graphics case and the frame case.

[0016] The closure means may be lids attachable to the respective cases.Alternatively, the closure means may be moulded features, mouldedunitarily with at least part of the respective case. The closure meansmay comprise at least one lid attachable to one of the graphics case andthe frame case, and at least one moulded feature, moulded unitarily withat least part of the respective frame case or graphics case.

[0017] The lower end piece of at least one of the frame case and thegraphics case may carry wheels for transporting the case.

[0018] The graphics case may have a substantially cylindrical outersurface. If so, the frame storage case may be substantially cylindrical,having a parallel, part cylindrical recess to complement the cylindricalouter surface of the graphics case. Alternatively, the frame storagecase may be shaped to have a recess to complement the cylindrical outersurface of the graphics case, and also shaped such that the framestorage case and the graphics storage case, when engaged, form asubstantially prismatic structure, with a cross-section which issubstantially oval, ovoid, or comprising two semicircular rounded partsjoined by substantially straight sides.

[0019] The frame case and/or the graphics case may be provided with atleast one reusable packing piece for retaining equipment within thecase.

[0020] The present invention also extends to a storage case for storageof a folded display stand, comprising at least one reusable packingpiece for retaining equipment within the case.

[0021] The present invention also extends to a reusable packing piecefor use in retaining equipment within a case for storage of a foldeddisplay stand. The packing piece may comprise at least one cut-out forretaining parts of the equipment, and/or at least one recess forretaining further parts of the equipment, when the equipment and thepacking piece are located within the case.

[0022] The packing piece may be constructed from a compressiblematerial. In its uncompressed state, the packing piece may have at leastone diameter which is greater than a corresponding internal diameter ofthe case, whereby the packing piece may be compressed into engagementwith an internal surface of the case.

[0023] The reusable packing piece may be for restraining equipmentwithin a roll of graphics, the packing piece having anessentially-cylindrical shape, with at least one cut-out providedtherethrough.

[0024] The packing piece may be constructed from a compressiblematerial. In its uncompressed state, it may have at least one diameterwhich is greater than a corresponding internal diameter of roll ofgraphics, whereby the packing piece may be compressed into engagementwith an internal surface of the roll of graphics.

[0025] The reusable packing piece may be made of polyurethane foam orpolyvinyl chloride foam or other plastics foam.

[0026] The reusable packing piece may comprise at least one cutoutforming a handle for manipulation of the packing piece

[0027] The present invention also extends to modular storage systemcomprising a modular storage case according to any described embodiment,together with one or more further graphics storage case, the graphicsstorage cases being interchangeably fastenable to the frame storagecase.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

[0041] The invention provides a modular storage case with separablecases. Typically, one case stores the frame, while another stores thegraphics. The graphics case is interchangeable with other graphics casesfor transport to a different exhibition, while avoiding the need tounpack any of the cases. This reduces the likelihood of damage to thegraphics and the frame by reducing the amount of handling required.Similarly, the invention also provides a modular storage system, whichincludes at least one frame storage case, and a number ofinterchangeable graphics storage cases.

[0042]FIG. 1 shows basic a modular storage case according to anembodiment of the present invention. As illustrated, a graphics case 1and a frame case 2 are provided.

[0043] The graphics case body 10 should be cylindrical, or at leastshould have a cylindrical inner cavity. This is to allow the graphics tobe effectively rolled up and stored. The cylindrical inner cavity may bedefined by a continuous cylindrical wall, or by a number of ribs tangentto an imaginary cylindrical surface.

[0044] According to an aspect of the present invention, the frame casebody 20 has an external cross-section which is complementary to theshape of the graphics storage case body. That is, in the illustratedembodiment, a part cylindrical recess 22 is provided, which is shaped toaccept a part of the outer surface of the graphics case body 10. Thegraphics case body and the frame case body are separable andindependent. End pieces 14, 16 are provided for closing upper and lowerends of the graphics case body. End pieces 24, 26 are provided forclosing upper and lower ends of the frame case body.

[0045] In use, a roll of graphics is placed inside the graphics case 1.The cylindrical inner cavity holds the roll in a stable position, andprotects it from damage. Preferably, nothing else which could causedamage to the graphics is stored in the graphics case. The folded frameis stored in the frame case 2. Packing materials may be provided withinthe frame case to prevent the frame from moving about inside the case,thereby protecting both the frame and the case from damage.

[0046] The frame case 2 may be detached from the graphics case 1 andattached to a similar graphics case containing an alternative set ofgraphics. This enables the graphics to be changed without requiring themto be unpacked, reducing the likelihood of damage.

[0047] Preferably, in a typical usage of the modular storage case of thepresent invention, nothing else should be stored in the graphics case.The graphics may be permanently stored in the graphics case, furtherreducing the risk of damage. The graphics case may be suitably labelledto identify the set of graphics it contains, facilitating retrieval ofthe graphics, and reducing the risk of damage since it is not necessaryto sort through a large number of stored graphics in order to retrieve adesired set.

[0048] According to a further aspect of the present invention, it may benecessary to store a frame, or frame parts or accessories, with thegraphics, in the graphics storage case. In such embodiments, packingpieces are provided to securely locate the frame, or parts andaccessories, so that they do not contact the graphics, eliminatingpotential damage to the graphics, and so that they do not move aboutinside the case when it is handled, reducing the risk of damage to theframe or the parts or accessories themselves. For example, if aparticularly small display stand is to be stored, the graphics and theframe may both be stored within the graphics case. Alternatively, with alarger display stand, it may be necessary to store some parts of theframe within the graphics case, if the frame case has insufficientcapacity to store all of the required frame parts.

[0049] According to a related aspect of the invention, a modular storagecase system comprises a frame case and a number of interchangeablegraphics storage cases.

[0050] Referring again to FIG. 1, end pieces 14, 16, 24, 26 serve toclose the ends of the case bodies, and to protect the contents.Preferably, as will be described in detail below, the end pieces alsoprovide means for engaging and fastening the frame case with thegraphics case.

[0051]FIG. 2 shows a cross-section of an embodiment of lower end pieces16, 26, which, in this embodiment, serve to close the lower end of theassociated case bodies and also to engage the cases together.

[0052] End piece 16 comprises a cylindrical, conical, truncated-conical,or other shaped boss 18 on its inner surface. End piece 26 needs no suchboss, since it serves to close the frame case, in which no rolls arestored, and which does not require any cavity to be provided on itsexternal surface, as described below.

[0053] A part of the external surface of the graphics case end piece 16comprises a cavity 19 whose shape corresponds to the corresponding partof the boss 18, preferably to form a constant wall thickness w in theregion of the boss.

[0054] The lower end-piece 26 for the frame storage case includes anoverlap portion 32, which is not required for closing the frame storagecase, since it lies outside of the perimeter of the frame storage casebody, shown by the location of the walls of the case body 20.

[0055] The overlap portion 32 is sized to overlap a part of theend-piece of the graphics case, including at least part of the cavity19, when the cases are placed together. The overlap portion alsocomprises a retaining lug 34, which is suitably dimensioned to locatewithin the cavity 19, when the cases are placed together. The lug 34which engages within the cavity 19, serves to engage the graphics caseand the frame case to each other.

[0056] The boss 18 allows space for a retaining lug 34 of sufficientsize to be accommodated within cavity 19, while nevertheless ensuringthat a roll of graphics 40 can be accommodated in a case of minimumheight. The minimum height requirement serves several purposes. There isa maximum height of case that can still fit in the boot (trunk) of acar. A case of this maximum height should be able to accommodate thetallest possible roll of graphics. Therefore, it is important that theroll of graphics 40 should extend as close to the end of the case aspossible. A roll of smaller graphics could be stored inside the roll 40,the end of the roll of smaller graphics resting on top of the boss 18.

[0057] The boss 18 therefore allows the roll of graphics 40 to extend aslow in the case as possible, while still providing a cavity 19. The bossmay also provide a support for any frame pieces of accessories which theuser may choose to store in the centre of the roll 40, as will befurther described below.

[0058] Preferably, similar end pieces with similar cavities, overlapportions and retaining lugs are provided at corresponding upper andlower ends of the cases. Then, the retaining lug 34 at each end will beretained in its cavity by the action of the retaining lug and cavity ofthe other end.

[0059] Alternatively, the upper end-piece of the graphics case may havea cavity, and corresponding boss on the internal surface, of onlysufficient size to accommodate a retaining lug 34. In such anembodiment, the space around the small boss may be used for storage ofancillary equipment and accessories, while a flat plate or foam layer isprovided to retain the ancillary equipment and accessories, whileproviding a safe surface for contacting the end of the roll of graphics40 without causing damage.

[0060] As illustrated in FIG. 2, the outer surface of the end piece forthe graphics case may include a recess 36, whose size, location anddepth at least correspond to the size, location and thickness of theoverlap portion 32 of the end piece for the frame case. This ensuresthat the graphics case will be stable when stood on end. In a similarcase of an upper end piece having recess only sufficient to accommodatethe retaining lug, the two end-pieces, when engaged, form asubstantially flat upper outer surface.

[0061] The substantially flat outer surface at the upper end of thecases will allow their top surfaces to be used as a counter on anexhibition stand.

[0062]FIGS. 3, 4 respectively show outer and inner surfaces of the endpieces of the graphics case and the frame case, when in engagement, suchas shown in FIG. 2.

[0063]FIG. 5A illustrates an end piece for a frame case, particularlysuitable for the lower end. It is similar to the one shown in FIG. 2. Inthis embodiment, the end piece is unitarily moulded (eg from a plasticsmaterial) with the lower part of the case body 20.

[0064]FIG. 5B illustrates an alternative end piece 24 particularlysuitable for the upper end of a frame case. While still similar to theend-piece shown in FIG. 2, this end piece is in the form of a detachablelid for the upper end of the frame case. The retaining lug 34 andoverlap portion 32 are as shown in FIG. 5A. The lid further compriseswall portions 20′ which may form part of the wall of the case. A ridgeor groove may be provided around the surface 21 to engage with acorresponding groove or ridge in the remainder of the wall portion 20.Alternatively, the wall portions 201 of the lid may be designed to slipover or partially inside the wall 20 of the case. Fastening means 23should be provided to retain the end piece (lid) in position. This maybe a latching clamp, as illustrated. This may also be lockable forsecurity reasons. Alternatively, straps with buckles or “Velcro”-typefastenings may be used, or features may be included in the lid and bodyto provide a snap-fit mechanism.

[0065] From consideration of FIGS. 1 and 2, it is clear that, by placingthe lid 24 in position, with its retaining lug in the cavity 19 of thegraphics case lid (14, FIG. 6C), both the graphics case and the framecase are retained together and closed by their respective lids. Thefastening means 23 then serves to hold the entire assembly together.

[0066]FIG. 6A shows a general end piece 14 for the graphics container. Acavity 19 is provided, and is at least sufficiently large to accommodatethe retaining lug 34 of the corresponding end piece of the frame case.Recess 36 is provided, to accommodate the overlap portion of the framecase. Cavity 19 extends into the graphics case, and is encased within aboss 18. Boss 18 may be a full cylindrical and/or truncated conicalboss, as shown. Alternatively, the boss may be only as large asnecessary to accommodate recess 19 with a wall thickness w. In use, theremainder of the surface of the end-piece 14 will serve either as a partof a substantially flat upper surface, which may be used as a counter,or serves as a lower surface on which the graphics case can stably restwhen stood on end.

[0067]FIG. 6B shows a lower end-piece for the graphics case. In thisexample, the end piece is unitarily moulded with part of the graphicscase wall 10. In this example, the boss 18 is a truncated-conical bossas discussed above. The cavity 19 occupies substantially all of the boss18, and is correspondingly truncated-conical in shape. The recess 36provided to accommodate the overlap portion 32 of the frame case hereextends over the entire area corresponding to the graphics case wall 10.Protrusions 31, 31′ are provided on opposite sides of the end-piece. Thelower surface of these protrusions serve as a stable base for standingthe graphics case on end. One protrusion 31 carries wheels 33 for use inmoving the case. The other protrusion 31′ serves as a rest. Preferably,the protrusions align with similar protrusions on the base of the framecase to provide a pleasing appearance when the cases are assembledtogether.

[0068]FIG. 6C shows an upper end-piece 14 for the graphics case. In thisexample, the end piece is in the form of a detachable lid. In aparticular embodiment, the lid may be used as a step stool to aid theassembly of the exhibition stand. Here, the cavity 19 is only largeenough to accommodate the retaining lug 34 of the frame case. The boss18 inside the lid is only large enough to accommodate the cavity 19.Similarly, the recess 36 is only large enough to accommodate the overlapportion 32 of the frame case.

[0069] Protrusions 35, 37 are provided on opposite sides of the lid.Protrusion 37 may comprise a handle, and should be arranged to locate onthe same side of the graphics case as the wheels 33 of FIG. 6B.Protrusion 35 is preferably provided, to increase the upper surface areaof the case for its use as a counter, and to increase the visual appealof the case. Protrusions 35, 37 preferably align with respectivelysimilar protrusions on the lid of the frame case.

[0070]FIG. 7A shows a perspective view of a graphics case and a framecase according to a certain embodiment of the invention. The frame caseand the graphics case are each shown assembled, but not linked together.Ribs 27 are shown, which protrude into the graphics case and serve todefine the substantially cylindrical internal storage space by animaginary cylindrical surface tangent to the internal extremities of theribs 27.

[0071]FIG. 7B illustrates the action of closing the frame case such thatthe overlap portion 32 of the end piece 24 of the frame case 2 engagesinto the recess 36 of the end piece 14 of the graphics case 1. Theretaining lug 34 locates within the cavity 19, thereby to engage thecases to each other. Fastening means 23 are then fastened, to retain thecases together, and to retain both end pieces 14, 24. A correspondinglug 34 on a corresponding overlap portion 32 at the lower end of theframe case 2 will already have been engaged into a cavity 19 at thelower end of the graphics case.

[0072] If the modular storage case of the invention is to be used as acounter, or other display piece for the stand, it should be wrapped in agraphic. The graphics case will have a height approximatelycorresponding to the height of the roll 40 of graphics, and so alsocorresponding to a dimension of a graphic. The outer surfaces of themodular storage case are preferably smoothly curved, to allow a graphicto be displayed in a pleasant manner, while avoiding damage to thegraphic. The embodiments shown in FIGS. 1 and 7 fulfil theserequirements by having a substantially prismatic structure, in this casehaving a cross section corresponding to two overlapping circles, or twosemicircles joined by straight sides, respectively.

[0073] Other embodiments of the invention may be provided, while stillfulfilling the above requirements. For example, prismatic structures maybe provided, having a cross section which corresponds to an oval, or anovoid. In each example, however, the graphics case should have acylindrical inner space for the storage of the graphics. This may meanthat the graphics storage case has a wall of varying thickness, or thatthe frame case is of an exotic cross section to accommodate acylindrical graphics storage case to provide the required shape of thecombined storage case.

[0074] In any of the above-described embodiments, and as furtherdescribed below in relation to a further aspect of the presentinvention, either or both of the graphics case and the frame storagecase may contain packing material for retaining a frame, or otherequipment, to avoid damage both to such equipment, the case, and anygraphics or other materials stored in the case. Several interchangeablesizes of packing pieces may be provided, to allow for storage of severaldifferent shapes of frame.

[0075] In a variant of the modular storage case of the presentinvention, two frame storage cases may be provided for each graphicsstorage case. For example, this would enable two exhibition frames andassociated graphics to be stored and transported together, typically twocomplementary frames and sets of graphics, which make up a single,larger, stand. The graphics case would, of course, need to be largeenough to hold two sets of graphics. To provide such a modular case, theoverlap and engagement features of the end pieces, if used, should berepeated on opposite sides. That is, the recess 36 and cavity 19 shouldbe provided on two, preferably diametrically opposed, parts of each endpiece for the graphics case. Similarly, the overlap portion 32 andengagement lug 34 should be provided on two, preferably diametricallyopposed, parts of each end piece for the frame case. Suitablearrangements must be made for all handles and wheels, if provided, toappear on the same or both sides of such a modular case. Even in such anembodiment, the case is preferably still small enough to fit into theboot of a car.

[0076] In any embodiments using recesses, cavities, lugs and overlapportions, filler pieces may be provided, corresponding to the overlapportion 32, including the lug 34, for use in obtaining flat outersurfaces to the end pieces of the graphics case, when the frame case(s)is/are not engaged to the graphics case.

[0077] In certain embodiments of the invention, the end pieces, beingclosure means for closing the upper and lower ends of the case walls,may be moulded unitarily with at least part of the respective case.Alternatively, the various end-pieces may be lids attachable to therespective ends of the respective cases.

[0078] In alternate embodiments of the modular storage case of theinvention, the overlap portions 32 and recesses 36 may take shapes otherthan that defined by overlapping circles shown in the figures Inaddition, the cases may be engaged to one another by other means, suchas other forms of co-operating features of the end pieces; mechanicallatches on the end pieces or on the walls; or straps and buckles,recessed into the outer surfaces of the case to allow a graphic to bewrapped around the outside of the case without being deformed by thestraps or buckles.

[0079] The end pieces may be attached to the case walls by the clamps orlatches described above, straps with buckles, “Velcro”-type fasteners ora snap-fit mechanism.

[0080] In certain embodiments of the invention, the end pieces for thelower end of the graphics case and the frame case may be provided withwheels to facilitate transport. Similarly, the case walls may beprovided with carrying handles.

[0081] In any of the above-described embodiments, and as furtherdescribed below in relation to a further aspect of the presentinvention, either or both of the graphics case and the frame storagecase may contain packing pieces for retaining a frame, or otherequipment, to avoid damage both to such equipment, the case, and anygraphics or other materials stored in the case. Several interchangeablesizes of packing pieces may be provided, to allow for storage of severaldifferent shapes of frame.

[0082]FIG. 8 shows an embodiment of storage cases according to an aspectof the present invention. Reusable packing pieces 50, 60 are locatedwithin the upper end pieces of the frame case and the graphics case,respectively. Each reusable packing piece may be made from a foammaterial such as polyurethane or other closed cell plastics foam.Typically, each packing piece will comprise a recess 52, 62 suitablydimensioned to retain an end of a folded frame stored within therespective case. Preferably, as will be further explained with referenceto FIGS. 11A and 11B, the packing pieces preferably do not fill theentire cross-section of the respective case, but voids may be includedin the material of the packing piece, or around the edges, to provide ahandle for easy insertion and removal of the packing pieces, or to allowlengthy pieces of equipment to be stored, protruding through the voidsin the packing piece, yet still restrained from excessive movement.

[0083] The packing pieces may be adapted to restrain other types ofarticle, not necessarily folded frames, within the cases.

[0084] As shown in FIG. 8, a space 64 may exist, above the packing piece60 in the graphics case 2. This may be used to store small accessories,fixtures and fittings. Further packing means (eg foam sheets) may beprovided to retain such items in the space 64.

[0085]FIG. 9 illustrates a graphics storage case provided with a packingpiece 70 according to a further embodiment of this aspect of the presentinvention. The packing piece 70 may again be constructed frompolyurethane or other closed cell plastics foam. The packing piece 70 isgenerally circular, and is designed to fit within the roll 40 ofgraphics. The packing piece 70 may have an external diametercorresponding to the outside diameter of the boss 18. The packing pieceincludes a hole 72 suitably dimensioned to accept the frame 80 to passtherethrough. Typically, a folded frame has an approximately squarecross section, and the hole 72 is shaped accordingly. Of course, ifdifferently shaped folded frames, or other objects, are to be storedwithin the roll 40, the hole 72 in the packing piece 70 will be shapedaccordingly. If required, several smaller holes 72 may be provided.

[0086] In an alternative embodiment, packing pieces such as 60 in FIG. 8may also be provided in the lower end piece of the graphics case. Inthis embodiment, and that shown on FIG. 8, the packing pieces may havethe undesired effect that either full height rolls 40 of graphics cannotbe stored, or that the overall height of the graphics case would have tobe increased to accommodate the packing pieces.

[0087]FIG. 11A shows a plan view of a packing piece 60 installed withina graphics case 2. The packing piece has a central recess 62 forretaining the folded frame (or other equipment) The packing piece isshaped to contact the wall 20 of the case at several points, with voids68 being provided by cut-outs of the packing piece. These voids allowlong pieces of equipment (eg magnetic rails used in assembly of thedisplay stand) to be stored in a controlled manner, preferably separatedfrom contact with the roll of graphics by careful sizing of the cutouts,and of the roll of graphics (eg by placing elastic bands around the rollof graphics). The cut-outs also allow the packing piece to have asufficient size (i.e. diameter/circumference) such that the contactpoints 69 are compressed into contact with the wall 20, while stillallowing the packing piece to be easily installed and removed. Thecut-outs may be used as handles.

[0088]FIG. 11B shows a plan view of a packing piece 70 for use in aframe case. It is similar in many respects to the packing piece 60 ofFIG. 11A. The packing piece has a central recess 72 for retaining thefolded frame (or other equipment). The packing piece is shaped tocontact the wall 10 of the case at several points, with voids 78 beingprovided by cut-outs of the packing piece. These voids allow long piecesof equipment (eg magnetic rails used in assembly of the display stand)to be stored in a controlled manner, preferably separated from contactwith the frame stored in the centre of the frame case 1, by carefulsizing of the cut-outs The cut-outs also allow the packing piece to besufficiently large that the contact points 79 are compressed intocontact with the wall 10, while still allowing the packing piece to beeasily installed and removed. A dedicated cut-out 80 may be provided foruse as a handle, or the other cut-outs may be so used.

[0089]FIGS. 12A and 12B respectively show perspective views of thepacking pieces 60, 70 of FIGS. 11A, 11B.

[0090] Although the use of packing pieces as described has beendescribed in relation to their use in conjunction with a modular storagecase according to an aspect of the present invention, the use of thepacking pieces is in no way limited to such use. Indeed, the packingpieces as described may be employed with any case for the storage andtransportation of folded display stands. This applies regardless ofwhether the frame is stored with, or separately from, the graphics 40.

[0091] The packing pieces will need to be shaped to fit into whichevercase they are intended to be used with, and will preferably be providedwith recesses to retain the frame or other equipment that they areintended to work with. The provision of cut-outs is optional, althoughthey are advantageous in allowing voids for the storage of lengthyarticles, handles for easy manipulation of the packing pieces, and toallow the packing pieces to be sized appropriately to be slightlycompressed when placed in the storage case, thereby to retain themselvesin position against the walls of the case.
